Pressure vessel plates common grades
We comply with authoritative global steel standards and classify our products by professional grades to achieve a precise match between material performance and industrial application scenarios. Our full range of steel products, covering plates, reinforcing steel bars, steel pipes and other categories, are all manufactured in strict accordance with the Chinese National Standard (GB), American Society for Testing and Materials (ASTM), British Standard (BS), German Industrial Standard (DIN) and Japanese Industrial Standard (JIS), meeting the requirements of all mainstream industrial grades.
Each steel grade is customized for specific performance characteristics: high-strength grades for construction engineering, high-toughness grades for pressure-bearing components, excellent weldability grades for fabrication and processing, and corrosion-resistant grades for harsh working conditions. We exercise strict control over chemical composition and metallographic structure during production to ensure that each batch of products meets the mechanical property indicators of the specified grade, with yield strength, tensile strength, elongation and impact toughness all complying with standard requirements.
Ranging from general-purpose plain carbon steel to high-alloy special steel for precision engineering, and from hot-rolled basic grades to cold-finished high-precision grades, our comprehensive grade system and standard-compliant production processes enable us to provide targeted material solutions for the construction, machinery manufacturing, petroleum and natural gas, pipeline engineering, automotive and other industries. All products are accompanied by detailed grade certification and standard test reports with traceable production quality, escorting your project construction and product manufacturing.
We conduct strict quality inspections on steel products, equipped with professional testing equipment and experienced testing teams.
